To. all whom it may concern:

Be it known that we, JAMES H. DANVER and \VILLIAM H. Loss, residents ofBeaver and Zelienople, respectively, in the counties of Beaver. andButler, respectively, State of Pennsylvania, have invented a new anduseful cast molds for bath-tubs, whereby the flasks and atterns whenbrought to position for forming such molds will be in perfect line toregister with each other and properly positioned in place, so that thepositioning of the molds with relation to each other will form an eventhickness of metal in the articlc' when cast.

v A Our invention consists, generally stated, in

the novel arrangement, construction and combination of parts, ashereinafter more specifically set forth and described and particularlypointed out in the claims.

Toenable others skilled in the art to which our invention appertains toconstruct and use our improved guiding device or means for moldingapparatus, we will describe the same more fully, referring to theaccompanying drawing, in which- Figure 1 is a plan view. of a templetfor use in connection with our invention. Fig. 2 is a side elevation ofthe same. Fig. 3 is a plan view of a bath-tub pattern showing thetemplet applied thereto. Fig. 4 is an enlarged plan view of a portion ofsaid pat tern and templet. Fig. 5 is an enlarged sectional view of aportion of the pattern and templet on the line 55 Fig. Fig. (i is asectional View of a portion of a flask showing the templet appliedthereto. Fig. 7 is a tional view of the pattern and in position. Fig. 8is an enlarged perspective view of the spool employed and showing indotted lines where the same is cut 'to form half portions for thepattern. Fig. il'is a like view of one of the half portions.

Like symbols of reference herein indicate like parts in each of thefigures of the drawing.

a pattern for forming bath-tubs, which is of the usual hollow shape andis provided with the lug portions 2 extending out from the match orstripping platel around saidpattern. Four of these lug portions :2 arepreferably employed, with two of the same located on each side of thepattern 1 near the ends thereof and each is provided with an opening 3through the same having an inner semi-circular portion 3 whichterminates in a tongue 2 extending over each side of the same and formedon said lug portions. The

usual drag flask for these molds is shown at i having the usual flange 5extending out from the upper end of the same and provided with theopenings or holes 6 through the same.

7 indicates a templet, which is preferably in the form of a frameprovided with a'central'opening 8 through the same and thereby formingthe sides 9 and ends 10 thereon. At each of the four corners of thetemplet 7 is located a pin 11 which is provided with a circular enlargedportion 12 extending above said templet and with the circular contractedportion 13 fitting within a circular hole 14 in said templet andextending below the same. These pins 11. are removably secured in placein the holes let-of the templet in any suitable manneryas by a pin orbolt 15 extending through said templet and the contracted portion 13 onsaid pins.

16 indicates a spool, preferably formed of metal, which is provided witha flange l? extending from each end'of the same and a circular openingor hole 18 through the same.

' The manner of constructing, use and operation of our improved guidingmeans for molding apparatus is as follows-In forming the guides a forthe pattern 1, two of the spools 1.6 are cut in half and on the dottedline 12) shown in Fig. 8, which will form four halves or segmentalbearing portions 20, such as is shown in Fig. 9, and after the teinplet7 has been placed under said pat-tern, as shown in Figs. 4: and 5, theenlarged portions l2 of the pins 11 on said templet will enter theopenings 3 in the lug portions 2 on said pattern. After this is done thesemi-circular bearing portions 20 are each placed in the semi-circularportions 3 of the openings 3 on the pattern 1 and against the enlargedportions 12 on the pins 11 insaid opening, so that tiny suitable fillingmaterial such as the Babbitt metal 21 can be placed in the spaces 22formed around said bearing portions 20 in the portions 3 of said openingto hold said bearing portions inplace, and after which the templet 7 andpins 11 are removed to form the pattern guides or seats 18 in saidportions 20 for the reception of the dowel pins hereinafter describedand from the holes 18' in the spools 16. In forming the guides for theflask 4:, four of the complete spools 16, like the one shown in- Fig. 8,are used, and these spools have their holes 18 slightly smaller indiameter than such holes for forming the guides 18 in the semicircularbearing portions 20. After the templet 7 has been placed on the flask 4,so that the contracted lower ends or portions 13 on the pins 11 carriedby said templet are within the holes 6 in the flange 5 or said flask,each of the spools 16 are placed in said holes and around said pinportions, and then a suitable filling material, such as the Babbittmetal 23 can be placed in the spaces 22 formed around said spools bysaid spools and holes to hold said spools in place, and after this isdone the tem let and pins are removed to form the ask guides orseats"18v for the dowel pins hereinafter described.

The dowel pins are shown at 24 and they are each provided with an upperenlarged pointed end portion 25 and a lower con- I flask and in suchlowering the guides or to its proper position on said flask and heprecis y matched therewith to form a mold, which will enable an eventhickness of metal to be had when the article is cast from such mold. I

It will be evident that our improved guiding device can be applied formatching any flask or pattern flasks and flasks or patterns,

life of the mold ports carrying the guiding means.

Various modifications and changes inthe design, arrangement andconstruction of our improved guiding device may be resorted to withoutdeparting from the spirit of the invention or sacrificing any of itsadvantages.

What we claim as our invention, and desire to secure by Letters Patent,is

1. Means for forming guiding seats in a molding device, comprising thecombination of a molding appliance having openings therein, with atemporary gage fitting in said openings, and bearing members secured insaid openings and around said gage for forming said seats.

2. Means for forming guiding seats in a molding device, comprising thecombination of a molding appliance having openings therein, with atemporary gage having pins thereon for fitting in said openings, andbearing members secured in said openings and around said pins forforming said seats.

Means for forming guidingseats in a molding device, comprisingthecombination of a molding appliance having openings therein, with atemporary gage havin shouldered pins thereon for fitting in saiopenings, and bearing members secured in said openings and around saidpins for forming said seats of different size.

4. Means for forming guiding seats in a molding device, comprising thecombination of a molding appliance having openings therein, with atemporary gage having removable pins thereon for fitting in saidopenings, and bearing memberssecured in said openings and around saidpins for forming said seats.

5. Means for forming guiding seats in a molding device, comprising thecombination of a molding appliance having openings therein, with atemporary gage having shouldered removable pins thereon for fitting insaid openings, and bearing members secured in said openings and aroundsaid pins for forming said seats of different size.

In testimony whereof, we, the said JAMES H. DANVER and WILLIAM H. Lose,have hereunto set our hands.
